Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589372, here are decompositions:

13 + 31589359 = 31589372
19 + 31589353 = 31589372
43 + 31589329 = 31589372
79 + 31589293 = 31589372
379 + 31588993 = 31589372
421 + 31588951 = 31589372
439 + 31588933 = 31589372
673 + 31588699 = 31589372

Showing the first eight; more decompositions exist.
